CVE-2024-10838: Eclipse Cyclone Data Distribution Service

Critical severity, CVSS 9.1. EPSS: 0.9% chance of exploitation in the next 30 days.

An integer underflow during deserialization may allow any unauthenticated user to read out of bounds heap memory. This may result into secret data or pointers revealing the layout of the address space to be included into a deserialized data structure, which may potentially lead to thread crashes or cause denial of service conditions.

Affected products
